Currently, hostapd_get_vlan_id_ifname() is used to determine if a given
vlan is valid *and* to actually determine the interface. This leads to
wpa_set_keys() sometimes setting the key on the wildcard interface name,
which does not make sense.
This patch therefore adds hostapd_vlan_id_valid() and makes
hostapd_get_vlan_id_ifname() not return a wildcard interface.

Currently, struct hostapd_vlan is a per-BSS data structure which
also contains informations about whether to remove the bridge
or clear wlan / tagged-vlan interface from the bridge.
In a multi-interface multi-BSS setup, this can lead to the following
race condition:
1. wlan0 creates VLAN A, sets DVLAN_CLEAN_BR and DVLAN_CLEAN_VLAN_PORT
2. wlan1 creates VLAN A, does not set DVLAN_CLEAN_BR and
DVLAN_CLEAN_VLAN_PORT as already there
3. wlan0 removes VLAN A, removes tagged-interface from the bridge
but not the bridge.
Now wlan1 VLAN A is unusable due to the missing uplink.
4. wlan1 removes VLAN A, does not cleanup
Solution:
This requires an inter-BSS inter-interface data structure to track the
bridge / bridge port usage within hostapd. This data structure could
also be used to track any other device-has-been-created-by-hostapd
information or when regarding interface freeing.

Currently by default, all BSS share the bridge brvlan%d.
While this is sane when no tagged-interface is given, this
is insane when different tagged interfaces are given, as
it would result in bridging those tagged interfaces.

and %d=VLAN ID as bridge name when a tagged-interface is given.

Commit c3fea27274 added a call to clear
all other PMKSA cache entries for the same network if the PMKSA cache
entry of the current AP changed. This was needed to fix OKC cases since
the other APs would likely use the new PMK in the future. However, this
ended up clearing entries in cases where that is not desired and this
resulted in needing additional full EAP authentication with networks
that did not support OKC if wpa_supplicant was configured to try to use
it.
Make PMKSA cache entry flushing more limited so that the other entries
are removed only if they used the old PMK that was replaced for the
current AP and only if that PMK had previously been used successfully
(i.e., opportunistic flag was already cleared back to 0 in

TDLS responder STA used to retransmit the TDLS Setup Response after 5
